That depends on which phone you’re upgrading from, and whether or not you’re someone who always wants the newest and shiniest (like me). Maybe specify which phone you have right now, so I can give you a better answer.
If it’s the S9+ or Note 9 you’ve got right now, then I’d say no. There’s nothing about the 10 line that blows away those phones so bad it’s worth upgrading. Now, if you have the S9, maybe you should think about upgrading, only because the S9 battery is so bad and the camera setup on the S10 is much better.
If you have the S8 line or any previous Galaxy phone, it might be worth upgrading, mostly because Samsung doesn’t support its phones very long.
